A. Construction and features of ball bearing mounted units.
NHK mounted ball bearing units consist of a double sealed, single row, deep groove ball bearing and any one of many types of housings.
The outer ring of the self-contained ball bearing is ground to a sphere along with the matching bore of the corresponding housing to provide self alignment capabilities.
Cylindrical outer ring ball bearings are also available.
B. Typical features of NHK ball bearing mounted units.
(1) Internal construction of single row deep groove bearings in mounted units.
The ball bearings used in mounted units are quite similar to the 6200 and 6300 series of single row, deep groove, radial ball bearings. These bearings are designed to operate under radial and to a lesser degree thrust loads and combined loads. They have considerably greater load carrying capacity than double row, self aligning bearings used in some other types of mounted units.
(2) Bearing materials.
52100 Bearing Grade Steel.
NHK bearings inner ring, outer ring and balls are made of 52100 vacuum degassed steel.
This high quality steel coupled with precision grinding and super finishing techniques increases bearing life and reduces bearing noise.
C. Seals used on Chrome Steel bearings.
Seal Materials Comparison:
BASE POLYMER:
NITRILE(NBR)
